Panic - Watchdog Timeout: no checkins from watchdogd in 185 seconds

Apple is working on a supplemental update containing a fix for the App Sandbox which caused a headache to many users because of a bug that killed virtualization apps.

Until the update arrives it's strongly recommended to stay away of virtualizers.

I have the same issue but it STARTED with 10.15.6.

2013 Mac Pro, kernel panic every night since 10.15.6. also happens during the day if the Mac Pro is idle long enough. I've reinstalled macOS from recovery, no luck.

Oddly, it also kills Messages, forcing me to log back in. Once it was unsuccessful, which is when I reinstalled macOS. That fixed Messages, but not the kernel panics.

I too have been experiencing these CPU Panic's since the 10.15.6 update.

I have a MBP 2018, connected via USB C to a Dell Monitor, and a Graphics Accellerator.

Since the 10.15.6 update the USB-C behaviour has been very patchy and I often have to pull the cable to my monitor and re-attach it to get the MBP to wake up.

I can see the mouse moving on both screens but it does not allow me to log in, and I have to hard shutdown the MBP.

And for a week or more, overnight now, I get the same CPU panic that brought me to this thread.

panic(cpu 2 caller 0xffffff7f873baad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds

Any solutions to this ?

I have the same problem, but it is infrequent. I have an "always on" iMac running 10.15.6 (Retina 5K, 27-inch, 2019, 3.6 GHz 8-Core Intel Core i9).

It seems to shutdown sometime overnight when it is in a rather quiescent state.

This iMac spontaneously shuts down every ~48 hours.

I can't correlate this directly to upgrading to 10.15.6, but it is definitely running 10.15.6.

Prior to this episode, this iMac would run without shutting down or rebooting for ~20-40 days at a time.

So far, it has not shutdown while I was actively using it.

Same issue as posted by everyone here.

panic(cpu 2 caller 0xffffff7f9e3c7ad5): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds

2013 Mac Pro running Catalina 10.15.6 with two Apple Thunderbolt displays, TimeMachine to external SSD, Avira Security software. Bluetooth keyboard, Anker wireless mouse with USB dongle.

Crashes happen at least daily, sometimes more often, no clear pattern to circumstances.

Have just installed the recommended 10.15.4 COMBO - will see if it makes any difference.

"..,Has been up continuously since I was allowed to get rid of McAFee ..."

It is good your employer saw sense in the end. Third party security apps always cause problems on Macs which have three level security built in.

The place for A/V in an enterprise is in the enterprise mail servers and firewalls to protect the Windows kit.

I just started getting these "panics" after upgrading to Catalina on my 2014 Mac Mini. I'm running Webroot, but it never "caused" any problems before, and it caught something once, some sort of threat, so I keep it. I installed the 10.15.6 Combo Update but I still get these.

They occur intermittently when I attempt to shut down, and it restarts instead saying there was this problem. Or an application will become unresponsive, and when I restart, I'll get it.

Including my latest report below, but I don't understand how to read it. Firefox had become unresponsive, so I force-quit, restarted, and got this.

Any thoughts?

Wonder if you all can help with this. Similar problem but I can run off an external HDD boot drive:

2014 iMac 32GB Catalina 10.15.7 1TB internal SSD encrypted with built-in FileSafe.

If I could just restore to my internal SSD...

• Started getting panic -watchdog timeouts yesterday for the first time
• They occur usually around 97 seconds after logging in, sometimes longer
• I cannot log on in safe mode. The machine takes forever and goes back to the login screen
• I disabled all energy savers
• I tried booting into recovery mode to reinstall MacOS (10.15.7). I do not see my internal SSD. I get "examining volumes" forever until the machine goes to a black screen
• To reinstall MacOS since recovery mode failed, I tried creating an external flash drive with the installcatalina app as instructed in another Apple Support page. When I boot up with option key down, I see that flash drive but it won't find my internal SSD ("examining volumes" never stops)
• I have a Time Machine backup. I can't restore it to my hard drive. When I boot off my internal SSD, the machine crashes before I can do anything.
• I restored my time machine backup (from before crashes started) to an external HDD and booted off that — which is how I am online now. It's horribly slow but it works. No crashes. I don't get kernel panics booting up in this external HDD.
• When booted up off my external HDD, I get an error message that my internal SSD is locked and can't be opened. I don't even see it in Disk Utility.

My latest Crash Report below. This is maddening. I saw the AppleSMC line below and did do an SMC reset.

Hi - I'm new to this message string but have been having (I think) the same problem... "Watchdog timeout..." since I bought this computer back in February. At first it would happen rarely - once every few days, and sometimes would go a few weeks, but for the past couple of days it's now every few minutes - mostly when I'm working in Lightroom. Don't know if anybody out there knows if there's an issue with Lightroom that might be causing this???

I did try to download and install the 10.15.4 combo update today, after reading that advice here. But I got an error message: "macOS Catalina 10.15.4 Update can't be installed on this disk. The volume does not meet the requirements for this update." I have macOS Catalina Version 10.15.7. Is there some other option I should try?

I'm by no means a computer / IT technician. My computer diagnostic skills and background consist of rebooting the machine and then yelling at it. Or vice versa. It seems like there should be a better way of getting help than having to put out messages into the "fellow users universe," and hoping that somebody out there has a clue what to do. Argh. Thanks to anybody out there for your answers. :)

I've been having these over a year from occasionally to every hour or so, but many signs point towards hardware failure:

* screen flickering increased from sporadically to constantly in a year (never dropped my mac (again) after apple replacement.

* batteries started bloating pushing screws out the mac (again, after another apple replacement)

* heat sync connector to mainboard is loose, was loose for over a year but seemed ok, crazy glued it tight 🤣

* pandemic replacement prevention syndrome struck 🙈

So I'd advice prayer if you're religious...

What means this message?

no checkins from watchdogd in 310 seconds

Actually, there was hope that 10.15.6 might have changes to help, not introduce new panic situations 😟

But I still want to thank you for your input.

I have the same problem... so, I has been talking with support but the answer is that I need still waiting a new release of Catalina... and my machine blocking each 3 hours...

I don’t use any virtualization apps nor an external monitor but I’m still having these kernel panics. Could this App Sandbox bug be the cause in this case?
